Periodic maintenance work
Water and dirt in the cartridge group
If water or dirt enters the cartridge group, this can impair the function of the
turbocharger and damage parts inside the cartridge group.
CAUTION
Make sure that no water or dirt enters the gap between partition wall and
turbine.
Non-permissible rotor unbalance after cleaning
Unevenly distributed residual contamination deposits lead to rotor unbal-
ance. This can result in bearing or turbocharger damage.
CAUTION
Remove all traces of contamination from the turbine.
After brushing off the dirt, fill the container (02) with clean water and not with salt water .
Immerse the turbine of the cartridge group in clean water so that any loose dirt comes off.
Lift up the cartridge group and align it horizontally.
Clamp the partition wall to the bearing casing.
Dry the turbine and the gap between the turbine and the partition wall with low-pressure
compressed air.
Lightly spray the turbine and the gap between the turbine and the partition wall with pene-
trating oil.
Dispose of dirty water and cleaning agents in accordance with the information in the mate-
rial safety data sheet.
